FIG. 1 is a schematic block diagram of a virtual reality (VR) system 10 in accordance with one embodiment of the present disclosure. In this embodiment, the VR system 10 includes a VR processing device 100, a VR display device 130, and a VR controller 140. In one embodiment, the VR processing device 100 may electrically connected to the VR display device 130 and the VR controller 140 via wired or wireless connection. In one embodiment, the VR processing device 100 may be integrated with the VR display device 130 or the VR controller 140, and the present disclosure is not limited to the embodiment described herein. In one embodiment, the VR system 10 may include more than one VR controllers. In one embodiment, the VR controller 140 may be omitted. In such a configuration, the VR system 10 may further include a detector to detect movements of the user.

In one embodiment, the VR system 10 may further includes base stations (not shown) for positioning the VR display device 130 and/or the VR controller 140 and/or detecting tilt angles (e.g., rotating angles or orientations) of the VR display device 130 and/or the VR controller 140. However, other positioning methods and/or orientation detecting methods are within the contemplated scope of the present disclosure.

In one embodiment, the VR processing device 100 includes one or more processing components 110 and a memory 120. In this embodiment, the processing component 110 is electrically connected to the memory 120. In one embodiment, the VR processing device 100 may further include signal transceivers for transmitting and receiving signals between the VR processing device 100 and the VR display device 130 and/or signals between the VR processing device 100 and the VR controller 140.

In one embodiment, the one or more processing components 110 can be realized by, for example, one or more processors, such as central processors and/or microprocessors, but are not limited in this regard. In one embodiment, the memory 120 includes one or more memory devices, each of which comprises, or a plurality of which collectively comprise a computer readable storage medium. The computer readable storage medium may include a read-only memory (ROM), a flash memory, a floppy disk, a hard disk, an optical disc, a flash disk, a flash drive, a tape, a database accessible from a network, and/or any storage medium with the same functionality that can be contemplated by persons of ordinary skill in the art to which this invention pertains. The VR display device 130 can be realized by, for example, a display, such as a liquid crystal display, or an active matrix organic light emitting display (AMOLED), but is not limited in this regard. The VR controller 140 can be realized by, for example, a handheld controller, such as a controller for Vive or a controller for Gear, but is not limited in this regard.

In one embodiment, the one or more processing components 110 may run or execute various software programs and/or sets of instructions stored in memory 120 to perform various functions for the VR processing device 100 and to process data.

In one embodiment, the one or more processing components 110 control the VR display device 130 to display a VR environment in a view of a first VR position in the VR environment. In one embodiment, a user's VR avatar may be at the first VR position in the VR environment. In one embodiment, the VR scene of the VR environment displayed by the VR display device 130 corresponds to the orientation and the position of the user's VR avatar (i.e., the orientation and the position of the VR display device 130). In one embodiment, the VR environment may have one or more VR objects therein.

In one embodiment, the one or more processing components 110 may detect a freezing operation at a certain moment (e.g., at the 15^(th) second). In one embodiment, the freezing operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at a freeze button) or a freeze gesture of the user (e.g., the user clenches his/her fists).

In one embodiment, in response to the freeze operation, the one or more processing components 110 freeze the VR environment at the certain moment (e.g., at the 15^(th) second), so that all of the one or more VR objects in the VR environment and the background of the VR environment are frozen and stop their motions or activities at the certain moment (e.g., the 15^(th) second). At this time, the one or more processing components 110 control the VR display device 130 to display this frozen moment of the VR environment in the view of the first VR position in the VR environment.

In one embodiment, after the VR environment is frozen, the one or more processing components 110 may detect a moving operation corresponding to a second VR position in the VR environment (e.g., at the 20^(th) second). In one embodiment, the moving operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at the second VR position) or a moving operation of the user (e.g., the user steps to a place corresponding to the second VR position).

In one embodiment, in response to the moving operation corresponding to the second position, the one or more processing components 110 control the VR display device 130 to display the frozen VR environment (e.g., frozen at the 15^(th) second) in a view of the second VR position in the VR environment.

Subsequently (e.g., at the 25^(th) second), the one or more processing components 110 may detect an unfreezing operation. In one embodiment, the unfreezing operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at an unfreeze button) or a unfreeze gesture of the user (e.g., the user looses his/her fists).

In one embodiment, in response to the unfreeze operation, the one or more processing components 110 unfreeze the VR environment so that all of the one or more VR objects in the VR environment the background of the VR environment are unfrozen and continue their motions or activities. In one embodiment, the one or more processing components 110 may move the user's VR avatar in response to the moving operation during the VR environment is frozen. In such an embodiment, the user's VR avatar is at the place where the user's VR avatar is moved to during the VR environment is frozen (e.g., the second VR position) while the VR environment is unfrozen.

In an alternative embodiment, the one or more processing components 110 may merely move a ghost of the user's VR avatar in response to the moving operation during the VR environment is frozen, in which the ghost of the user's VR avatar indicates a virtual character controlled by the user that can move around during the VR environment is frozen. In such an embodiment, the VR scene of the VR environment displayed by the VR display device 130 corresponds to the orientation and the position of the ghost of the user's VR avatar (i.e., the orientation and the position of the VR display device 130) during the VR environment is frozen. In such an embodiment, the ghost of the user's VR avatar disappears while the VR environment is unfrozen, and the VR display device 130 displays the VR environment corresponding to the orientation and the position of the original user's VR avatar again.

FIG. 2 illustrates an illustrative example of the VR system in accordance with one embodiment of the present disclosure. In this example, the VR environment VRN has a first VR object OB1 (e.g., a campfire) and a second VR object OB1 (e.g., a wall) therein. The user's VR avatar VAR is at VR position POS1 in the VR environment VRN. The one or more processing components 110 control the VR display device 130 to display the VR environment VRN in a view of the position POS1. Since the VR object OB1 is shielded by the VR object OB2, the object OB1 is not presented on the VR display device 130.

In this example, the user may freeze the VR environment VRN. During the VR environment VRN is frozen, the user can move his/her VR avatar or a ghost of his/her VR avatar to the VR position POS2, so that the VR display device 130 can display the VR environment VRN in a view of the position POS2. At this time, since the VR object OB1 exposes from the VR object OB2, the object OB1 can be presented on the VR display device 130.

Through the operations described above, the user can explore all of the VR environment at a certain moment by freezing the VR environment at that moment.

In one embodiment, during the VR environment is frozen, the one or more processing components 110 may change one or more parameters of one or more of the VR objects in the frozen VR environment in response to a movement of the user's VR avatar or the ghost of the user's VR avatar. In one embodiment, the movement may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at a VR object) or a motion of the user (e.g., the user stretches out his/her hand to a VR object). In one embodiment, the one or more parameters may include one or more position parameters, one or more orientation parameters, one or more motion parameters, and/or one or more statue parameters, but are not limited in this regard.

FIGS. 3A and 3B illustrate an illustrative example of the VR system in accordance with one embodiment of the present disclosure. In this example, the user may click at the frozen object OB1, so that the user's avatar or the ghost of the user's avatar perform a movement corresponding to the frozen object OB1, so as to change one or more parameters corresponding to the frozen object OB1 (e.g., change a corresponding statue parameter from “light up” to “extinguished”).

In one embodiment, during the VR environment is frozen, the one or more processing components 110 may change one or more parameters of one or more of the user's VR avatar in the frozen VR environment in response to a movement of the ghost of the user's VR avatar. In one embodiment, the movement may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at the user's VR avatar) or a motion of the user (e.g., the user stretches out his/her hand to the user's VR avatar). In one embodiment, the one or more parameters may include one or more position parameters, one or more orientation parameters, one or more motion parameters, and/or one or more statue parameters, but are not limited in this regard.

FIG. 4 illustrates an illustrative example of the VR system in accordance with one embodiment of the present disclosure. In this example, the user may click at the frozen user's VR avatar VAR, so that the ghost of the user's avatar perform a movement corresponding to the frozen user's VR avatar VAR, so as to change one or more parameters corresponding to the frozen user's VR avatar VAR (e.g., change a corresponding position parameter).

In one embodiment of the present disclosure, after the one or more processing components 110 control the VR display device 130 to display the VR environment in the view of a first VR position in the VR environment, the one or more processing components 110 can detect a capturing operation at a certain moment (e.g., at the 15^(th) second). In one embodiment, the capturing operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at a capturing button) or a capturing gesture of the user (e.g., the user clenches his/her fists).

In one embodiment, in response to the capturing operation, the one or more processing components 110 capture the VR environment at the certain moment (e.g., the 15^(th) second) that store information of the VR environment corresponding to this certain moment to the memory 120. In one embodiment, the stored information may include information of the background of the VR environment corresponding to this certain moment, information of the one or more VR objects in the VR environment corresponding to this certain moment, and/or information of the user's VR avatar corresponding to this certain moment. In one embodiment, the VR environment is captured as a global VR image. In one embodiment, after the global VR image is captured, the one or more processing components 110 can continuously perform the VR application corresponding to the VR environment and/or capture another global VR image.

In one embodiment, after the global VR image is captured (e.g., at the 35^(th) second), the one or more processing components 110 can retrieve the information of the VR environment captured at the certain moment (e.g., the 15^(th) second) to display that moment of the VR environment in the view of the first VR position according to the retrieved information.

Subsequently (e.g., at the 40^(th) second), the one or more processing components 110 may detect a moving operation corresponding to a second VR position in the VR environment. Details of the moving operation can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

In response to the moving operation corresponding to the second position, the one or more processing components 110 control the VR display device 130 to display the captured moment of the VR environment (e.g., captured at the 15^(th) second) in a view of the second VR position in the VR environment.

That is, instead of merely a 2D image, the global VR image is a certain moment of the VR environment corresponding to the capturing time point that the user's VR avatar or the ghost of the user's VR avatar can move around therein.

In one embodiment, the one or more processing components 110 may move the user's VR avatar in response to the moving operation in the captured moment of the VR environment (i.e., in the global VR image). In an alternative embodiment, the one or more processing components 110 may merely move the ghost of the user's VR avatar in response to the moving operation in the captured moment of the VR environment. In such an embodiment, the VR scene of the VR environment displayed by the VR display device 130 corresponds to the orientation and the position of the ghost of the user's VR avatar in the captured moment of the VR environment. Details of the ghost of the user's VR avatar can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

In one embodiment, within the certain moment of the VR environment, the one or more processing components 110 may change one or more parameters of one or more of the VR objects in the captured moment of the VR environment in response to a movement of the user's VR avatar or the ghost of the user's VR avatar. Many aspects in this regard can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

In one embodiment, within the certain moment of the VR environment, the one or more processing components 110 may change one or more parameters of the user's VR avatar in the captured moment of the VR environment in response to a movement of the user's VR avatar or the ghost of the user's VR avatar. Many aspects in this regard can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

Through the operations described above, a moment of the VR environment can be captured and redisplayed.

In one embodiment of the present disclosure, the one or more processing components 110 control the VR display device 130 to display a VR event in a view of a first VR position in a VR environment in a first period (e.g., 5^(th)-15^(th) seconds). In one embodiment, a user's VR avatar may be at the first VR position in the VR environment. In one embodiment, the VR scene of the VR environment displayed by the VR display device 130 corresponds to the orientation and the position of the user's VR avatar (i.e., the orientation and the position of the VR display device 130). In one embodiment, the VR environment may have one or more VR objects therein. In one embodiment, the VR event indicates one or more motions of the user's VR avatar, one or more activities of the background of the VR environment, and/or one or more motions of the one or more VR objects in the VR environment.

In one embodiment, the one or more processing components 110 record the VR event that store information of the VR event in the VR environment during the first period to the memory 120. In one embodiment, the stored information may include information of the activities of the background of the VR environment in the VR event during the first period, information of the one or more motions of the one or more VR objects in the VR environment in the VR event during the first period, and/or information of the one or more motions of the user's VR avatar in the VR event during the first period.

In one embodiment, after the VR event is recorded, the one or more processing components 110 may detect a redisplay operation corresponding to the recorded VR event (e.g., at the 25^(th) second). In one embodiment, the redisplay operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at a redisplay button corresponding to the recorded VR event) or a redisplay operation of the user (e.g., the user stretches out his/her hand to a redisplay button corresponding to the recorded VR event).

In one embodiment, in response to the redisplay operation corresponding to the recorded VR event, the one or more processing components 110 control the VR display device 130 to redisplay the recorded VR event in a view of a second VR position in the VR environment in a second period (e.g., in the 25^(th)-30^(th) seconds). In one embodiment, the redisplayed VR event includes the recorded activities of the background of the VR environment, the recorded one or more motions of the one or more VR objects in the VR environment, and/or the recorded one or more motions of the user's VR avatar in the VR event during the first period.

In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), the present user's VR avatar may be at the second VR position different from the first VR position. In addition, in the same time, the VR display device 130 may redisplay the past user's VR avatar at the first VR position in the first period in the view of the second VR position.

In one embodiment, during the second period (e.g., in the 25^(th)-30^(th) seconds), the one or more processing components 110 may detect a moving operation corresponding to a third VR position different from the second VR position in the VR environment (e.g., at the 27^(th) second). In one embodiment, the moving operation may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at the third VR position) or a moving operation of the user (e.g., the user steps to a place corresponding to the third VR position).

In one embodiment, in response to the moving operation corresponding to the third position, the one or more processing components 110 control the VR display device 130 to display the recorded VR event in a view of the third VR position in the VR environment. In one embodiment, the one or more processing components 110 moves the user's VR avatar to the third VR position in the VR environment in response to the moving operation corresponding to the third position. That is, in the second period (e.g., in the 25^(th)-30^(th) seconds), the user's VR avatar can move around to watch the redisplayed VR event at different places.

In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), the one or more processing components 110 may freeze the VR environment at the certain moment (e.g., the 27^(th) second), so that all of the redisplayed VR objects in the VR environment, the redisplayed background of the VR environment, and the redisplayed user's VR avatar are frozen at the certain moment (e.g., the 27^(th) second). Details in this regard can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), the one or more processing components 110 may capture the VR environment at the certain moment (e.g., the 27^(th) second) that store information of the VR environment corresponding to this certain time point to the memory 120. In one embodiment, the stored information may include information of the redisplayed background of the VR environment corresponding to this certain moment, information of the redisplayed one or more VR objects in the VR environment corresponding to this certain moment, and/or information of the redisplayed user's VR avatar, and/or the present user's VR avatar corresponding to this certain moment. In one embodiment, the VR environment is captured as a global VR image.

In one embodiment, after the global VR image is captured (e.g., at the 35^(th) second), the one or more processing components 110 can retrieve the information of the VR environment captured at the certain time point (e.g., the 27^(th) second) to display that moment of the VR environment according to the retrieved information.

It should be noted that, details of the capture operation in the second period described above can be ascertained with reference to the paragraphs above, and a description in this regard will not be repeated herein.

In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under an observer mode, movements of the user's VR avatar do not affect the redisplayed VR event. In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under the observer mode, movements of the user's VR avatar do not change any parameter of the one or more of the redisplayed VR objects and/or the redisplayed user's VR avatar recorded in the first period.

Similarly, in one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under the observer mode, movements in the redisplayed VR event do not affect the redisplayed VR event. In one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under the observer mode, movements of the one or more of redisplayed VR objects and/or the redisplayed user's VR avatar recorded in the first period do not change any parameter of the user's VR avatar.

In an alternative embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under an interacting mode, movements of the user's VR avatar change one or more parameters of the one or more of the redisplayed VR objects and/or the redisplayed user's VR avatar recorded in the first period. Similarly, in one embodiment, in the second period (e.g., in the 25^(th)-30^(th) seconds), under the interacting mode, a motion of the one or more of the redisplayed VR objects and/or a motion of the redisplayed user's VR avatar recorded in the first period change one or more parameters of user's VR avatar.

In one embodiment, the one or more parameters may include one or more position parameters, one or more orientation parameters, one or more motion parameters, and/or one or more statue parameters, but are not limited in this regard.

In one embodiment, the one or more processing components 110 can enable the observer mode or the interacting mode according to a default setting or a user's selection. In one embodiment, the user's selection may be performed by the VR controller 140 (e.g., a click of the VR controller 140 aiming at an observer mode button or an interacting mode button) or a selecting operation of the user (e.g., the user stretches out his/her hand to an observer mode button or an interacting mode button).

FIG. 5 illustrates an illustrative example of the VR system in accordance with one embodiment of the present disclosure. In this example, in a first period (e.g., 5^(th)-15^(th) seconds), there is a VR event that the user's VR avatar VAR1 fights with a VR object OB3 (e.g., a VR character), and a VR object OB4 is positioned beneath the user's VR avatar VAR1 in the VR environment VRN. This VR event is recorded and afterward redisplayed in a second period (e.g., in the 25^(th)-30^(th) seconds).

In the second period, the present user avatar PVAR is at the VR position POS1, and the VR display device 130 redisplays the recorded actions of the past user's VR avatar VAR1 and the recorded actions of the VR object OB3 in the VR event in the view of the VR position POS1.

In the second period, in the observer mode, the present user's VR avatar PVAR can move to another VR position (e.g., the VR position POS2) to watch the redisplayed event in the view of the another VR position.

On the other hand, in the interacting mode, in addition to moving around, the present user's VR avatar PVAR can pick up the VR object OB4 (e.g., change one or more position parameters thereof), attack the VR object OB3 (e.g., change one or more statue parameters (e.g., health parameters) thereof), and/or attack the past user's VR avatar VAR1 (e.g., change one or more statue parameters (e.g., health parameters) thereof). Similarly, the recorded motions of the past user's VR avatar VAR1 and/or the recorded motions of the VR object OB3 in the VR event may also damage the present user's VR avatar PVAR (e.g., change one or more statue parameters (e.g., health parameters) thereof).

In one embodiment, in the interacting mode, the one or more processing components 110 may also change the recorded motions of the past user's VR avatar VAR1 and/or the recorded motions of the VR object OB3 corresponding to a movement of the present user's VR avatar PVAR corresponding to the past user's VR avatar VAR1 and/or the VR object OB3. For example, when the present user's VR avatar PVAR swings at the VR object OB3, the VR object OB3 may defend this attack, instead of continuously fighting with the past user's VR avatar VAR1 as recorded.
